R. RAMSAY Dec. 8, 1953 TOY BOAT Filed Sept. 29, 1950 Inventor Raou?Ramsay 3f/MJ Attorney Patented Dec. 8, 1953 UNITED STATES PATENT OFFICEd t v 2,661,571 l l TOY B'OAT Raoul Ramsay, Cut Knife;SaskatchewamCanada Application September 29,E 1950, Serial No. 187,468

VThis invention relates to toys and more par- "ticularly to a liquidpropelled toy boat.

said chamber consists of a cylinder within which .is disposed a springloaded piston which causes the liquid to be expelled therefrom to propelthe toy boat.

The primary object of the invention is therefore to provide a novelliquid propelled toy boat which may be adjusted to operate in circles orin a straight line or in reverse direction.

A further object is to provide means whereby the liquid is not permittedto escape while the chamber is being lled.

Still another object is to provide an adjustable rudder so that thedevice may be operated in a straight or curved line or in reversedirection.

With these and other objects in view that may appear as the descriptionproceeds, the invention consists in the novel arrangement of cooperatingelements as hereinafter more specifically set forth, claimed and shownin the accompanying drawing forming part of this application and inwhich:

Fig.l 1 is a side elevational view of a toy boat constructed inaccordance with my invention;

Fig. 2 is an enlarged detailed view of the inlet to the liquid chamber.

Fig. 3 is a detailed view of the rudder;

Fig. 4 is a rear elevational view of the rudder;

Fig. 5 is a detail of the pump to fill the fluid chamber.

Referring more in detail to the drawing in which similar referencecharacters designate corresponding parts throughout the several views itwill be seen the invention comprises a toy boat 5 having a hull 6 and acylinder 'I formed within the hull.` The cylinder comprises a piston 8mounted on a rod 9 and a compression spring I0, at the rear of thepiston. The said rod extends through the rear Wall of the boat and isformed with a knob II by means of which the piston is brought back andthe spring I9 compressed when the cylinder 1 is lled with liquid.

The liquid enters the cylinder by means of an aperture I2 normallyclosed by a ball check valve I3 to prevent the liquid from escapingtherefrom when said liquid is under pressure.

The piston 8 is slidably mounted on the rod 9 so that when the cylinderis lled with liquid 5 Claims. (Cl. 46--95) l the rod may be pushed backto its original posi- 1 tion and held therein by means of a projecting istud I3 formed on the rod which lits into an L-shaped groove I4 formedon a plug extension I5 formed integral with the rear wall of the hull.The liquid is expelled from the cylinder 1 by the piston, throughchannel I5a extending from the forward end of the cylinderlongitudinally of the hull. The channel Ilia extends into a cylindricalextension formed integral with the rear end of the hull on which collarI8 is rotatably mounted.

A tube 20 having its upper end tted in the I collar I8 has a passage Iltherethrough adapted to register with the channel lia when the tube isin a vertical depending position. A rudder I6 is rotatably mounted onthe lower end of the tube 20 to swing about the axis of the tube and thepassage I1 through the tube at its lower end communicates with thehorizontal passage I9 in the rudder through which the liquid isdischarged. Upon swinging the rudder upwardly, as shown in dotted linesin Fig. 4, the channel I5a and passage I1 are moved out of registerwhich shuts oil' the flow of liquid through the rudder.

To steer the direction of the boat the rudder I6 is turned about theaxis of the tube 20 on which it is rotatably mounted and if the rudderis turned from the position shown in Fig. 1, the liquid will bedischarged from the passage I9 in a forward direction thus driving theboat in a reverse direction.

It is believed that the construction and advantages of the structureshown may be apparent from the foregoing paragraphs taken in conjunctionwith the accompanying drawings without further detailed description.

While the preferred embodiment of the invention has been disclosed it isunderstood that minor changes in the details of construction,combination and arrangement of co-operating parts may be resorted towithin the scope of what is claimed withoutedeparting from the spirit ofthe invention.

I claim:

1. A toy boat comprising a hull having a pair of parallel longitudinalpassages in communication at one end, a spring actuated piston mountedto reciprocate in one of said passages, the other passage being open atthe rear end of said hull, means for retracting said piston, and meansfor introducing liquid into said passages, said piston when releasedoperating to expel the liquid from said passages.

2. A toy boat comprising a hull having a 1ongitudinal bore, a, secondbore parallel to said first mentioned bore and communicating therewithat one end, the opposite end of said second bore being open at the rearend of said hull, means for introducing liquid into said bores, a springactuated piston mounted to reciprocate in said first-mentioned bore, andmeans for retractng said piston, said piston when released operating toexpel the liquid in Vsaid bores from the open end of 'saidsecondementioned bore.

3. A toy boat comprising a hull having a 1ongitudinal bore, a secondbore parallel to said rstmentioned bore and communicating therewith-atone end, the opposite end of said second bore extending into anextension iii'th'e ra' er'id f said hull, a rudder pivotally mounted onthe rear end. of said hull having a passage Vtherethrough open: ingthrough the rear edge of the rudder, said second bore havingcommunication with the pas- 'sage 'through said rudder, means forintroducing liquid. into said bores, ,a spring actuated piston mountedin said first-mentioned bore, and means :for retracting said piston,said piston when -released operating to expel the liquid in said bores lthrough the passage in said rudder.

'4. A toy boat comprising a hull having a longitudinal bore, a secondbore parallel to said first-mentioned bore having communicationtherewith at its front vend, an extension. on the rear end of said hullhaving a passage therethrough with one end in communication with thevre'ar 'end of said second bore, a collar rotatably mounted on saidextension having an opening adapted at times to register with theVVVpassage in the extension, a tube having one end tted in the opening ofsaid collar extending radially from said collar, a rudder rotatablymounted on said tube to rotate about its axis. said rudder having apassage extending from said tube through the rear edge of the rudder,means for introducing liquid into said bores, a spring actuated pistonmounted in said first- 'm'nti'hed b'r,r and ifieais' rtifating saidpiston, said piston lreleased loperating to expel said liquid from saidbores and through the Tpassage of said rudder.

5. A toy boat comprising a hull having parallel longitudinal passages incommunication at n'eendaiidldaptii to receive a liquid, a piston mountedto reciprocate in one of said passages, 'the other passage" openingthrough the rear end of said hull for admitting liquid into saidpassages upon movement f the piston in one direction,and a spring formoving said piston in the opposite directionuto expel the liquid fromthe open end of the other passageiwm M RAQUL RMSAY.
